Solution Overview

Problem

Conventional clean in place (CIP) methods for removing soils from hard surfaces in industrial applications, such as food and beverage processing, require high temperatures, leading to energy and water wastage and inefficiency in removing tenacious soils like carbohydrate, protein, and fat residues.

Innovation Solution

A method involving the application of a composition containing an activator complex, a source of alkalinity, and an active oxygen source at reduced temperatures (5°C to 50°C), which generates oxygen gas in situ to break down and remove soils, reducing the need for high heat and chemical usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional clean in place methods use high temperatures to remove tenacious soils, then cleaning effectiveness is improved, but energy consumption and water consumption increase

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent changes the temperature parameter from high (conventional) to low (invention), and compensates by changing the chemical composition parameters - specifically introducing activator complexes with transition metals and peroxide compositions that enable effective cleaning at lower temperatures through enhanced chemical reactivity rather than thermal energy

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces the thermal mechanism (heat-based cleaning) with a chemical mechanism (activator complex and peroxide reaction). Instead of relying on high temperature to break down soils, the invention uses chemical reactions between the activator complex and peroxide to generate reactive oxygen species that chemically degrade soils at lower temperatures

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If conventional clean in place methods use high temperatures to remove soils, then cleaning effectiveness is improved, but water consumption increases

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidwater consumption
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent changes the temperature parameter from high to low, and compensates by optimizing chemical composition parameters. The activator complex and peroxide formulation is designed to work effectively at lower temperatures, reducing the need for large volumes of hot water for both application and rinsing

Inventive Principle:
Principle #35Parameter changes

3Reliability

If conventional methods use high chemical usage to remove tenacious soils, then cleaning effectiveness is improved, but chemical consumption increases

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidchemical consumption
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent creates a composite cleaning system combining the activator complex (containing transition metals) with peroxide compositions. This composite material works synergistically - the activator complex enhances the reactivity of the peroxide, generating reactive oxygen species that are much more effective at breaking down tenacious soils than either component alone, thereby reducing overall chemical consumption

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent employs strong oxidizing action through the reaction between the activator complex and peroxide, which generates reactive oxygen species. This accelerated oxidation process rapidly breaks down carbohydrate, protein, and fat soils that are resistant to conventional cleaning, achieving effective soil removal with reduced chemical quantities

Inventive Principle:
Principle #38Strong oxidants (Accelerated oxidation)
